Are the following sentences natural to a native ear?
1. I am just opening the file, please bear with me for a second.
2. Actually I have a sweet tooth, but I try hard to avoid eating anything sweet.
3. The only knock against this project is that it is not as inclusive as some other programs.
The first one is a comma splice. You need a period or a semi-colon or a "so" -- but not a comma between the two parts.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
'The only knock against this project. . . ' does not sound natural to me.
It is not something I have heard before or would ever use.
To use "knock" to mean "say something negative" you would need something like:
The only thing I could say to knock this project is that it is not as inclusive as some other programs.
"To knock" is commonly used in BrE in this way.
